Ah.. Sussed it about 5 minutes posting...
It required removing the "checked" attribute from the tag, rather than
changing the value of it:
if (extra.getExtraPassengers().contains(pax)) {
tag.put("checked", "checked");
} else {
tag.remove("checked");
}
Cheers

Subject: Problems with lists of checkboxes...
Hi...
I've been having lots of fun trying to get a list of checkboxes to
display correctly on a page. What I am attempting to do is to display a
list of checkboxes based on a list of passengers and when the checkbox
is checked, add the selected passenger to another object.
I had great fun trying to figure out why all of the checkboxes are
checked all of the time and was hoping that overriding the
onComponentTag and attempting to set checked as true/false or even
checked/unchecked based on a condition might help, but to no avail. I'm
probably missing something really simple, but need pointing in the right
direction.
CheckGroup group = new CheckGroup("group", passengers) {
@Override
protected void onSelectionChanged(final Collection
newSelection) {
Extra extra = (Extra) getParent().getModelObject();
List<Passenger> pax = extra.getExtraPassengers();
List<Passenger> selection = (List<Passenger>)
newSelection;
if (pax.containsAll(selection)) {
pax.removeAll(selection);
} else {
pax.addAll(selection);
}
}
@Override
protected boolean wantOnSelectionChangedNotifications() {
return true;
}
};
ListView people = new ListView("people", passengers) {
@Override
protected void populateItem(final ListItem item) {
final Passenger pax = (Passenger) item.getModelObject();
Check check = new Check("checkbox", item.getModel()) {
@Override
protected void onComponentTag(final ComponentTag
tag) {
super.onComponentTag(tag);
if (extra.getExtraPassengers().contains(pax)) {
tag.put("checked", "checked");
} else {
tag.put("checked", "unchecked");
}
}
};
item.add(check);
item.add(new Label("name", pax.getDefaultDetails()));
}
};
people.setReuseItems(true);
group.add(people);
extraItem.add(group);
boolean displaySelected = extra.isSelectedExtra();
group.setVisible(displaySelected);
Regards
Andrew
